单片机 12864 LCD显示--按键电子时钟程序

12864使用说明一、串/并接口1.1 串口接口管脚信号*注释1：如在实际应用中仅使用并口通讯模式，可将PSB 接固定高电平。

*注释2：模块内部接有上电复位电路，因此在不需要经常复位的场合可将该端悬空。

*注释3：如背光和模块共用一个电源，可以将模块上的JA、JK 用焊锡短接。

1.2 并行接口管脚信号*注释1：如在实际应用中仅使用并口通讯模式，可将PSB 接固定高电平。

*注释2：模块内部接有上电复位电路，因此在不需要经常复位的场合可将该端悬空。

*注释3：如背光和模块共用一个电源，可以将模块上的JA、JK 用焊锡短接。

二、模块主要硬件构成说明控制器接口信号说明：2.1、RS，R/W的配合选择决定控制界面的4种模式：2.2、E信号●忙标志BFBF 标志提供内部工作情况.BF=1 表示模块在进行内部操作,此时模块不接受外部指令和数据.BF=0 时, 模块为准备状态,随时可接受外部指令和数据.利用STATUS RD 指令,可以将BF 读到DB7 总线,从而检验模块之工作状态.●字型产生ROM（CGROM）字型产生ROM（CGROM）提供8192 个此触发器是用于模块屏幕显示开和关的控制。

DFF=1 为开显示（DISPLAY ON),DDRAM 的内容就显示在屏幕上，DFF=0 为关显示（DISPLAY OFF)。

DFF 的状态是指令DISPLAY ON/OFF 和RST 信号控制的。

●显示数据RAM（DDRAM）模块内部显示数据 RAM 提供 64×2 个位元组的空间，最多可控制 4 行 16 字（64 个字）的中文字型显示，当写入显示数据 RAM 时，可分别显示 CGROM 与CGRAM 的字型；此模块可显示三种字型，分别是半角英、数字型(16*8)、CGRAM 字型及 CGROM 的中文字型。

三种字型的选择，由在 DDRAM 中写入的编码选择，在0000H—0006H 的编码中（其代码分别是0000、0002、0004、0006 共4 个）将选择 CGRAM 的自定义字型，02H—7FH 的编码中将选择半角英数字的字型，至于A1 以上的编码将自动的结合下一个位元组，组成两个位元组的编码形成中文字型的编码BIG5（A140—D75F），GB（A1A0-F7FFH）。

12864时钟显示程序/*用LCD12864液晶显示器进行设置时钟，有独立键盘调节时间程序*/个人觉得在学习编写LCD12864显示程序时可以多结合1602一起来学习，很多东西是相通的，我这个程序就是，还有对于初学者来说，最好是理解程序每个模块的作用，掌握后对于以后的编程学习进度会更快，再补充说明一句，对于显示模块程序，着重需要对地址些函数部分理解，废话不多说，看程序吧：#include#define uchar unsigned char#define uint unsigned intsbit RS= P2^6;//数据/命令选择端(H/L)sbit RW= P2^5;//读写/选择端(H/L)sbit EP= P2^7;//使能信号sbit K1=P3^0; //开关定义sbit K2=P3^1;sbit K3=P3^2;uchar num,t;uchar K1num;char s,f,m; //可取负数uchar code table[]= " 2013-8-12 MON ";//日期显示uchar code table1[]=" 00: 00: 00 AM "; //时间显示uchar code table2[]="长沙今日多云"; //天气显示uchar code table3[]=" 南风39-30℃"; //气温显示void init1(); //中断子函数void delay(uint k) //延时函数{uint i,j;for(i=k;i>0;i--)for(j=110;j>0;j--);}void write(uchar com) //命令指令函数{ //根据时序图来设置RS=0; //选择指令寄存器RW=0; //选择写P0=com; //将8位数据通过P0口传给12864delay(5); //延时一会，让12864准备接收数据EP=1; //使能线电平变化，数据送入1602的八位数据口delay(5);EP=0;}void read(uchar date) //写入指令函数{ //根据时序图来设置RS=1; //选择寄存器RW=0; //选择写P0=date; //将8位数据通过P0口传给12864delay(5);EP=1;delay(5);EP=0;}void init() //初始化函数{RS=0;EP=0;RW=0;write(0x38); //显示设置模式write(0x0c); //显示开关控制write(0x06); //光标设置write(0x01); //清屏设置write(0x80); //数据地址初始位for(num=0;num<16;num++) //查table表数据{read(table[num]); //读取表中内容delay(20);}write(0x90);//重新设置数据指针for(num=0;num<16;num++) //查table2表数据{read(table2[num]); //读取表中内容delay(20);}write(0x98);//重新设置数据指针for(num=0;num<16;num++) //查table3表数据{read(table3[num]); //读取表中内容delay(20);}write(0x88);//重新设置数据指针for(num=0;num<16;num++){read(table1[num]); //读取table1表中内容delay(20);}}void write_sfm(uchar add,uchar date) // 时分秒函数设置{ uchar shi ,ge;shi=date/10; // 取商ge=date%10; //取余write(0x83+add); //设置add位地置read(0x30+shi); //设置十位地置read(0x30+ge); //设置个位地址}void key() //独立开关控制{if(K1==0){delay(5);if(K1==0){K1num++;while(!K1); //判断按键是否按下if(K1num==1) //按一下调节秒{TR0=0; //关定时器write(0x83+10); //找到秒位置write(0x0f); //光标闪烁}}if(K1num==2){write(0x83+8);//再按一下调节分地址}if(K1num==3) //第三次按下调节时{write(0x83+6);}if(K1num==4) //按四次回到正常计时{K1num=0;write(0x0c);//光标不闪TR0=1;}}if(K1num!=0) //有按下{if(K2==0) //K2开关控制时分秒加{delay(5);if(K2==0) //消抖{while(!K2);//松手if(K1num==1) //秒调节{m++;if(m==60)m=0;write_sfm(10,m);write(0x83+10);//秒钟地址}if(K1num==2) //分钟调节{f++;if(f==60)f=0;write_sfm(8,f);write(0x83+8); //分钟地址}if(K1num==3) //小时调节{s++;if(s==23)s=0;write_sfm(6,s);write(0x83+6);//时地址}}}if(K3==0){delay(5);if(K3==0){while(!K3);if(K1num==1) //K3控制时分秒减{m--;if(m==-1)m=59;write_sfm(10,m);write(0x83+10);}if(K1num==2)f--;if(f==-1)f=59;write_sfm(8,f);write(0x83+8);}if(K1num==3){s--;if(s==-1)m=23;write_sfm(6,s);write(0x83+6);}}}}}void main() //主函数{init(); //调用子函数init1(); //调用定时子函数while(1){key();}}void init1() //定时子函数{TMOD=0x01;EA=1; //开总中断ET0=1; //开定时器中断TR0=1;TH0=(65536-50000)/256; //设置时间50ms TL0=(65536-50000)%256;}void e() interrupt 1 //定时器T0方式1中断{ TH0=(65536-50000)/256;TL0=(65536-50000)%256;t++;if(t==18) //一秒钟定时{m++;if(m==60) //秒设置{m=0;f++;if(f==60) //分设置{f=0;s++;if(s==24) //小时设置{s=0;}write_sfm(6,s); //时位数据读取}write_sfm(8,f); //分位数据读取}write_sfm(10,m); //秒位数据读取}}。

LCD12864液晶显示电子钟设计
介绍：
设计目标：
设计一个能够实时显示时间和日期的电子钟，能够精确地获取当前的时间，并对用户的操作作出相应的响应。

设计原理：
该电子钟设计采用了单片机ATmega16作为核心，配合RTC（实时时钟）模块，通过控制液晶显示屏来显示时间和日期。

硬件设计：
1.电源电路：使用直流电源电压为5V，通过稳压芯片将输入电压稳定在5V。

2.单片机电路：将ATmega16与晶振、复位电路、电源电路等连接起来。

3.RTC电路：通过连接RTC芯片和单片机，实现对实时时钟的读取和控制功能。

4.液晶显示屏电路：将液晶显示屏与单片机进行连接，通过单片机控制液晶显示屏的显示。

软件设计：
1.初始化：对单片机和RTC进行初始化设置。

2.获取时间：从RTC读取当前时间和日期。

3.显示时间：将获取到的时间和日期分别显示在液晶显示屏的相应位置。

4.操作功能：通过按键控制，实现对时间和日期的调整和设置功能。

设计步骤：
1.确定电路设计需求和所需元器件。

2.搭建硬件电路，完成电路连接。

3.使用相关软件进行单片机和RTC的编程设置。

4.测试整个电路是否能够正确工作，如对时间进行调整并观察液晶显示屏的显示是否准确。

5.根据需求进行适当的优化和完善设计。

总结：。

简介：第一行显示，距离系统爆炸时间第二行显示，还剩第三行显示，00时，00分，00秒第四行显示，周林按下旋钮开关，开始设定秒，秒编辑位闪动。

左右旋转设定数值，在按下开关，秒确定，设定分，分编辑位闪动左右调数值，再按下，分确定，小时位闪动。

左右转调小时，再按一下。

时间确定，开始倒计时。

《单片机原理及应用》课程设计说明书题目LCD12864 液晶显示电子钟设计系(部)专业(班级)姓名学号指导教师起止日期课程设计任务书系(部)：专业：课题名称LCD12864 液晶显示电子钟设计设计要求设计一种基于AT89S52 单片机的液晶显示电子时钟，要求如下：（1）、能正确显示时间、日期和星期显示格式为：时间：XX 小时：XX 分：XX 秒；日期：XX 年：XX 月：XX 日；星期：X。

（2）、时间能够由按键调整，误差小于1S。

（3）、闹钟功能：时间运行到与闹钟设定时间时，闹钟响（持续响3 秒）。

（4）、报时功能：时间运行到正点时间时，闹钟响，几点钟就响几声（每声持续响 2 秒，每两声之间时间间隔 1 秒）。

液晶显示器第一行显示“数字电子钟”；第二行显示“当前时间”；第三行显示日期和星期；第四行显示最近一个闹钟的设定时间。

2、要求：完成该系统的硬件和软件的设计，在Proteus 软件上仿真通过，并提交一篇课程设计说明书。
